**v0.2.1** — Now with lean **mining_dopamine** reward signal.

A lightweight, zero-unsafe Rust crate for neuromorphic computing. Designed as the official Rust backend for **Spikenaut-v2** — the 16-channel neuromorphic HFT + FPGA system.

## Features

- LIF + Izhikevich neurons
- Reward-modulated STDP learning
- Full neuromodulator system (dopamine, cortisol, acetylcholine, tempo, **mining_dopamine**)
- Lean MiningReward EMA calculation (no heavy dependencies)
- Sub-1 µs modulator updates
- ~1.6 KB memory footprint
- no_std + Q8.8 fixed-point FPGA .mem export ready
- jlrs zero-copy interop for Julia training

## Quick Start

```rust
use neuromod::{SpikingNetwork, NeuroModulators, MiningReward, HftReward};

let mut network = SpikingNetwork::new();

// 16-channel telemetry stimuli
let stimuli = [0.5f32; 16];

// Create modulators + mining reward
let mut reward = MiningReward::new();
let mining_dopamine = reward.compute(hashrate, power_draw, gpu_temp);

let modulators = NeuroModulators {
    dopamine: 0.7,
    cortisol: 0.3,
    acetylcholine: 0.6,
    tempo: 1.0,
    mining_dopamine,  // ← new in v0.2.1
};

let spikes = network.step(&stimuli, &modulators);
```

## Architecture

### Neuron Banks (16 channels)
- 8 bear/bull asset pairs (DNX, QUAI, QUBIC, KASPA, XMR, OCEAN, VERUS + thermal)
- Coincidence detector + global inhibitor

### Neuromodulator System
- **Dopamine** – market/sync reward
- **Cortisol** – stress/inhibition
- **Acetylcholine** – focus/SNR
- **Tempo** – clock scaling
- **mining_dopamine** (v0.2.1) – EMA-smoothed mining efficiency reward

### HftReward Trait
```rust
pub trait HftReward {
    fn sync_bonus(&self) -> f32;
    fn price_reflex(&self) -> f32;
    fn thermal_pain(&self) -> f32;
    fn mining_efficiency_bonus(&self) -> f32;  // new
}
```

## Performance

- Latency: **< 1 µs** per step
- Memory: **~1.6 KB** full network
- Throughput: > 1M steps/sec on single core
- FPGA-ready: Q8.8 fixed-point export
